Leng Hui, a social worker, died suddenly while working overtime. When he woke up, he found that he had become the captain of the Space Guard and the eldest brother of the Ultra Brothers, Zoffie. Facing the legendary Ultraman who came to call him "Big Brother" one after another, and the ardent expectations from Ultra's father, Leng Hui was under great pressure. He doesn't understand combat or light. The only thing he has is the memory of having read all the scripts as a tokusatsu fan. Thus, the most "prophetic" Captain Zoffie in history was born. He must rely on information gaps to grow from a fake to a truly upright captain of the Space Guard without exposing his rookie nature.
